The 2020 United States Senate elections were held on November 3, 2020, [1] with the 33 class 2 seats of the Senate contested in regular elections. [2] Of these, 21 were held by Republicans, and 12 by Democrats. The winners were elected to 6-year terms from January 3, 2021, to January 3, 2027. [3] Two special elections for seats held by Republicans were also held in conjunction with the general elections: one in Arizona, to fill the vacancy created by John McCain's death in 2018; and one in Georgia, following Johnny Isakson's resignation in 2019. [4] [5] [6] [7] These elections ran concurrently with the 2020 United States presidential election in which incumbent president Donald Trump lost to Democratic nominee Joe Biden.

In the 2014 United States Senate elections, the last regularly scheduled elections for Class 2 Senate seats, the Republicans won nine seats from the Democrats and gained a majority, [8] which they continued to hold after the 2016 and 2018 elections. [9] [10] Before the elections, Republicans held 53 seats, Democrats held 45 seats, and independents caucusing with the Democrats held two seats, neither of which were up for re-election. [11] Including the special elections in Arizona and Georgia, Republicans defended 23 seats, and the Democrats defended 12. [12]

In this election, the Democratic Party made a net gain of three Senate seats and the vice presidency, giving them a majority for the first time since 2014, albeit by a narrow 50–50 margin. [a] [13] Democrats unseated four Republicans in Arizona, Colorado, and both elections in Georgia – while Republicans flipped a seat in Alabama; however, Democrats under-performed expectations overall; despite record-breaking turnout and fund-raising efforts, they failed to flip several seats that were considered competitive, and lost many races by much larger margins than expected. [6] [14] Except in Maine, the winning party in every Senate election was the winning party in the state's presidential election. [15]

Due to election laws in Georgia that require candidates to win at least 50% of the vote in the general election, the state's regularly scheduled and special Senate elections were decided in run-off elections on January 5, 2021. [16] After the November general election, Republicans held 50 seats, while Democrats held 48 and the vice presidency, so sweeping both races was crucial for Democrats to attain a majority. They succeeded in doing so, [7] and the partisan balance in the Senate became tied for the third time in history, after the results in the 1880 elections and the 2000 elections. [17] [18] Vice President Kamala Harris's tie-breaking vote gave Democrats control of the chamber by the smallest margin possible after the new administration took office. [19]

This marked the first time since 1980 that either chamber of Congress flipped partisan control in a presidential election year, and the first time Democrats did so since 1948. [20]

Change in composition

Republicans defended 23 seats, while Democrats defended 12. [12] Each block represents one of the 100 Senate seats. "D#" is a Democratic senator, "I#" is an independent senator, and "R#" is a Republican senator. They are arranged so that the parties are separated, and a majority is clear by crossing the middle.

Before the elections

Each block indicates an incumbent senator's actions going into the election. Both Independents caucus with the Democrats.

Final pre-election predictions

Several sites and individuals published predictions of competitive seats. These predictions looked at factors such as the strength of the incumbent (if the incumbent was running for re-election) and the other candidates, and the state's partisan lean (reflected in part by the state's Cook Partisan Voting Index rating). The predictions assigned ratings to each seat, indicating the predicted advantage that a party had in winning that seat. Most election predictors used:

Tommy Tuberville
Republican

Incumbent Democrat Doug Jones was elected in a special election in 2017, narrowly defeating Republican nominee Roy Moore. [90] [91] He ran for a full term in 2020, losing to Republican Tommy Tuberville in a landslide.

Tuberville is a former football head coach for Auburn University. He defeated former senator and attorney general Jeff Sessions in a July 14 run-off to secure the Republican nomination, after securing President Donald Trump's endorsement. Sessions occupied the seat until 2017 when he resigned to become attorney general in the Trump administration.

Alabama is one of the country's most Republican states, and Jones's win was in part due to sexual assault allegations against nominee Roy Moore during the special election; most analysts expected the seat to flip back to GOP control. Tuberville defeated Jones by more than 20 percentage points. [92]

Potential Democratic candidates included Begich, who was the Democratic nominee for governor of Alaska in 2018, and Anchorage mayor Ethan Berkowitz, who was the Democratic nominee for governor of Alaska in 2010. One Democrat, Edgar Blatchford, filed to run by the June 1 filing deadline. [96]

Gross, an orthopedic surgeon and fisherman, declared his candidacy on July 2, 2019, as an independent. [97] He participated in a joint primary for the Alaska Democratic Party, Alaska Libertarian Party and Alaskan Independence Party, winning the nomination as an independent supported by the Democratic Party.

Despite predictions of a close race, Sullivan defeated Gross by 12.7 percentage points. [98]

Six-term Republican John McCain was re-elected in 2016, but died in office on August 25, 2018, after a battle with brain cancer. [101] Republican governor Doug Ducey appointed former senator Jon Kyl to fill the seat temporarily. [102] After Kyl stepped down at the end of the year, Ducey appointed outgoing U.S. Representative Martha McSally to replace him after she lost the election to the other Arizona senate seat. [103] McSally ran in the 2020 special election to fill the remaining two years of the term, [104] losing to Democrat Mark Kelly, a former astronaut.

Once a solidly Republican state, Arizona trended more purple in the late 2010s. Incumbent Republican Martha McSally was appointed to the late John McCain's seat two months after losing the 2018 Arizona U.S. Senate election to Democrat Kyrsten Sinema. Her Democratic opponent, astronaut Mark Kelly, raised significantly more money and generally led her by 5 to 15 points in the polling. McSally also suffered from low approval ratings due to her strong allegiance to Trump, who was unpopular in Arizona despite having won the state by 3.5 points in 2016. [105]

One-term Republican Cory Gardner was elected in 2014 after serving four years in the United States House of Representatives, narrowly defeating one-term Democrat Mark Udall. Gardner sought a second term but lost to Democrat John Hickenlooper by 9.3 percentage points. [115]

Hickenlooper is a popular former governor of Colorado, and led Gardner by as much as 20 percentage points in polls, with most pundits considering him a heavy favorite. Gardner was Colorado's only Republican statewide officeholder, and the once purple state has trended increasingly Democratic since his narrow win in 2014. Gardner also had low approval ratings due to his strong allegiance to Trump, who lost Colorado in 2016 to Hillary Clinton by 4.9%, and in 2020 to Joe Biden by 13.5%. [116] [117] Hickenlooper also raised significantly more money than Gardner. [118]

Georgia

Due to Republican senator Johnny Isakson's resignation from office for health reasons in 2019, both of Georgia's Senate seats were up for election in November 2020. [125] The state had tilted Republican in Senate races since the mid-1990s, but increased support for Democrats in populous suburbs has made office elections more competitive; a close governor's race, multiple close U.S. House races, and many other close local office races resulted in Democratic gains in 2018 elections. Both the regular and special election were considered highly competitive toss-ups. [126] Both of these elections received national attention, as if Republicans won at least one of these seats, they would maintain a Senate majority, but if the Democrats won both, the Senate would be split 50/50 with Vice President Kamala Harris breaking the tie.

Elected U.S. Senator

Raphael Warnock

Three-term senator Johnny Isakson announced on August 28, 2019, that he would resign from the Senate on December 31, 2019, citing health concerns. [135] Georgia governor Brian Kemp appointed Republican Kelly Loeffler to replace Isakson until a special election could be held; Loeffler took office on January 6, 2020, and competed in the November 2020 election to retain her seat. [136]

Other Republicans who ran for the seat included Wayne Johnson, former chief operating officer of the Office of Federal Student Aid, [137] and four-term U.S. representative Doug Collins. [138]

A "jungle primary" was held November 3, 2020, but no candidate won more than 50% of the vote, so a run-off election between the top two finishers, Loeffler and Democratic challenger Raphael Warnock, was held on January 5, 2021. [139] Warnock defeated Loeffler, who initially refused to concede and vowed to challenge the outcome, [140] but conceded on January 7, after the storming of the U.S. Capitol. [141]

Ernst's popularity had dropped in polls, and many considered this seat a possible Democratic pick-up, but Ernst was re-elected by a larger-than-expected 6.5 points.

Four-term Republican Pat Roberts, was re-elected in 2014 with 53.15% of the vote, and announced on January 4, 2019, that he would not be running for re-election in 2020.

In the Republican primary, United States representative Roger Marshall defeated former Kansas secretary of state Kris Kobach, [157] state Turnpike Authority chairman Dave Lindstrom, [158] state senate president Susan Wagle, and others. [159]

There was considerable speculation about a Senate bid by Mike Pompeo (the United States secretary of state, former director of the Central Intelligence Agency, and former U.S. representative for Kansas's 4th congressional district), but he did not run. [160] [161]

Barbara Bollier, a state senator and former Republican, [162] defeated former congressional candidate Robert Tillman [163] for the Democratic nomination, but lost to Marshall with a more than expected 11.4 point margin.

Republican Susan Collins won a fifth term in office, defeating Speaker of the Maine House of Representatives Sara Gideon. [170]

Gideon consistently led Collins in polls for almost the entire election cycle. Collins is considered one of the most moderate Republicans in the Senate and had never faced a competitive re-election campaign, even though Maine leans Democratic. But she faced growing unpopularity due to her increasingly conservative voting record, and her votes to confirm Brett Kavanaugh to the Supreme Court and to acquit Trump in his impeachment trial. Despite almost all polling and Gideon's formidable funding, [171] Collins was re-elected by a surprising 8.6-point margin.

Educator and activist Lisa Savage also ran as a candidate for the Green party. [172]

Democrat Ed Markey was re-elected in 2014, having won a 2013 special election to replace long-time incumbent John Kerry, who resigned to become U.S. secretary of state. He easily won a second full term in 2020, defeating Republican Kevin O'Connor by more than 33 percentage points. [176]

Markey fended off a primary challenge from Joe Kennedy III, four-term U.S. representative for Massachusetts's Fourth District and grandson of former U.S. senator and U.S. attorney general Robert F. Kennedy. This marked the first time a member of the Kennedy family lost an election in Massachusetts. [177]

O'Connor defeated Shiva Ayyadurai, a former independent senate candidate, in the Republican primary. [178] [179]

On August 24, 2020, perennial candidate Vermin Supreme launched a write-in campaign for the Libertarian nomination, [180] but received too few votes to qualify for the general election ballot. [181]

Steve Daines
Republican

Republican Steve Daines won a second term in office, defeating the Democratic nominee, Montana Governor Steve Bullock. [196]

Daines was opposed (before his nomination) in the Republican primary by hardware store manager Daniel Larson and former Democratic speaker of the Montana House of Representatives John Driscoll, who changed parties in 2020. [197]

Bullock won the Democratic nomination, [198] defeating nuclear engineer and U.S. Navy veteran John Mues. [199]

Libertarian and Green party candidates were set to appear on the general election ballot, but the Libertarians refused to nominate a replacement after their nominee withdrew and the Greens' nominee was disqualified.

Once Bullock filed his candidacy, the race became seen as highly competitive. Bullock, a popular governor and a moderate, led in many polls in the spring and summer of 2020, and raised more money than Daines. Closer to election day, Bullock slightly trailed in polls, but the election was still seen as relatively competitive. Daines defeated Bullock by a larger-than-expected 10-point margin.

Republican Ben Sasse easily won a second term in office, defeating Democrat Chris Janicek by more than 30 percentage points. [202]

Sasse had defeated businessman and former Lancaster County Republican Party chair Matt Innis in the Republican primary with 75.2% of the vote.

Businessman and 2018 U.S. Senate candidate Chris Janicek won the Democratic primary with 30.7% of the vote, defeating six other candidates.

Libertarian candidate Gene Siadek also appeared on the general election ballot.

After the primary election, the Nebraska Democratic party withdrew its support from Janicek when allegations that he sexually harassed a campaign staffer emerged. [203] Janicek refused to leave the race despite the state party endorsing his former primary opponent,[ clarification needed ] which led former Democratic Congressman Brad Ashford to announce a write-in campaign on August 23, 2020. [204] [205] After Janicek vowed to remain in the race anyway, Ashford withdrew on August 27, citing lack of time and resources necessary for a U.S. Senate campaign. [206] The state Democratic Party subsequently threw its support behind long-time Nebraska activist Preston Love Jr., who declared a write-in candidacy for the seat. [207] [208]

Booker had sought his party's nomination for President of the United States in 2020. He suspended his presidential campaign on January 13, 2020, and confirmed his intention to seek a second Senate term. [219]

Attorney Rik Mehta defeated engineer Hirsh Singh, 2018 Independent U.S. Senate candidate Tricia Flanagan, 2018 independent U.S. Senate candidate Natalie Lynn Rivera, and Eugene Anagnos for the Republican nomination.

Green Party candidate Madelyn Hoffman and two independent candidates also appeared on the general election ballot.

New Jersey has not elected a Republican senator since 1972, and all pundits expected Booker to be easily re-elected. [220]

Three-term Republican Lindsey Graham won a fourth term in office, defeating Democrat Jaime Harrison by over ten percentage points in a highly publicized race.

Graham defeated three opponents in the June 9 Republican primary. [245]

After his primary opponents dropped out, former South Carolina Democratic Party chairman Jaime Harrison was unopposed for the Democratic nomination.

Bill Bledsoe won the Constitution Party nomination. On October 1, 2020, Bledsoe dropped out of the race and endorsed Graham, but remained on the ballot as required by state law. [246]

Despite the significant Republican lean of the state as a whole, polls indicated that the Senate election was competitive, with summer polling ranging from a tie to a modest advantage for Graham. [247] [248] Graham's popularity had declined as a result of his close embrace of Trump, reversing his outspoken criticism of Trump in the 2016 campaign. [249] [250]

Graham's victory was by a much larger margin than expected, [251] as part of a broader pattern of Republicans overperforming polls in 2020.

Republican John Cornyn won a fourth [267] term in office, defeating Democrat MJ Hegar by a little less than ten percentage points.

Cornyn defeated four other candidates in the Republican primary, with 76.04% of the vote.

Hegar, an Air Force combat veteran and the 2018 Democratic nominee for Texas's 31st congressional district, [268] defeated runner-up state senator Royce West and 11 other candidates in the Democratic primary. Hegar and West advanced to a primary run-off election on July 14 to decide the nomination, and Hegar prevailed.

The Green and Libertarian Parties also appeared on the general election ballot. Candidates from the Human Rights Party and the People over Politics Party and three independents failed to qualify.

Statewide races in Texas have been growing more competitive in recent years, and polling in August/September showed Cornyn with a lead of 4–10 points over Hegar, with a significant fraction of the electorate still undecided. [269] [270] Cornyn's victory was at the higher end of the polling spectrum.

A write-in candidate is a candidate whose name does not appear on the ballot but seeks election by asking voters to cast a vote for the candidate by physically writing in the person's name on the ballot. Depending on electoral law it may be possible to win an election by winning a sufficient number of such write-in votes, which count equally as if the person were formally listed on the ballot.
